Vandal-resistant fluorescent fixture

Abstract

The cover for the fixture comprises an opaque base having a cylindrical outer wall formed with a slightly lesser-diameter neck terminating in an outward-extending bead. Fitting on the base is a translucent cover having a truncated conical top and a cylindrical wall of the same diameter as the base. The rim of the cover wall has an inward extending bead and a groove inward of the bead. The beads of cover and base interfit to prevent separation except at one location where the base bead is interrupted and there is a slot in the outer wall for a blade or coin to be inserted to pry the cover off. The cover and base are of impact-resistant, slightly flexible plastic. Within the base is a metal mounting for a ring-type fluorescent lamp and its ballast and starter and also a fitting for mounting the base on a wall or ceiling or on an adapter to fit on a pole.

What is claimed is: 
     
       1. A lighting fixture comprising an integral base having a cylindrical outer wall having a co-planar edge adapted to fit flush against a wall or ceiling, an inset projection on the end of said outer wall opposite said edge, said inset projection being formed with a base bead and a base groove inward of said bead, said base bead being formed with a short, arcuate interrupted portion, , said outer wall being formed with a slot suitable for insertion and twisting of a blade or coin, said slot being immediately inward of said interrupted portion of said bead; an integral translucent cover having a cylindrical outer cover wall of the same diameter as said outer wall of said base, the inner surface of said cover wall being formed with a cover bead and a cover groove inward of said cover bead, said cover bead being adapted to fit in said base groove and said base head being adapted to fit in said cover groove; said base and cover being made of impact-resistant, slightly flexible plastic material; a fixture mounting attached to said base a short distance below said co-planar edge having an uppermost outer disk shaped for attachment to a conventional junction box, an inner disk below and parallel to said outer disk; screw means connecting said disks together, a bracket fixed to said inner disk, resilient clips fixed to said bracket, a ring-type fluorescent fixture held in said clips, a ballast, a starter, and means attaching said socket, ballast and starter to said bracket. 
     
     
       2. A lighting fixture according to claim 1 which said base is formed with an inward-slanted wall having an annular flange at its inner end, said inner disk fitting on top of said annular flange. 
     
     
       3. A lighting fixture according to claim 1 which further comprises a junction box having a conduit terminating therein and conduit wires in said conduit, said box having an outer face, means detachably connecting said outer disk to said outer face, fixture wires extending from said box into said base and connected to said socket, and connectors in said box connecting said conduit wires to said fixture wires, said outer wall of said base enclosing said box. 
     
     
       4. A lighting fixture according to claim 1 which further comprises a post, a post socket fitting on top of said post, an outward-inward slanted flange on said post socket, said annular flange of said base resting on said slanted flange, a pair of wings outside said post socket, the outer edge of each wing bearing down on said annular flange, and a screw threaded into each said wing and extending through said slanted flange and having a bead below said slanted flange, whereby by turning the head of said screw said wing is drawn down to clamp said annular flange tightly to said slanted flange.
